Individual variation in response to stressors in farm animals: Implication for experimenters

Several ways of reducing stress during experiments are suggested and the need for skillful and humane handling is emphasized. .. Any modification of the handling procedure aimed at reducing its stressful nature would be beneficial. .. It is concluded that...

Facial and vocal discrimination in sheep

The ability of sheep,Ovis aries, to discriminate between sheep, humans and other animals on the basis of facial and vocal cues was tested in an enclosed Y-maze. Pairs of faces or voices were presented which had a clear differential significance...

The experimental Animal in Biomedical Research (Vol. II) – Care, Husbandry, and Well-Being: Sheep

Probably more than other species, they [sheep] require social company in order to cope with the circumstances of their domestication and in particular with the confinement under an experimental situation. It therefore follows that, in accommodating these animals for purposes...

Effects of an enriched environment on subsequent fear reactions of lambs and their mothers

From birth to weaning (3 months of age), 20 lambs were reared by their mothers in an enriched environment [colored mobile objects plus human-like figure]. Subsequently, this resulted in reduced fear reactions in the mothers, but not in the lambs.
